Specification of Letters Intent. Application and June 3, 190a. serial No. 438,520.

Patented Jan. 18, 1910.

Be it known that 1, DAVID RODREICK, a citizen of the United States, resident of San Diego, in the county of San Diego, State of California, have-invented a new and useful "acuum and Flushing Apparatus, of which the following is a specification. j'.

My invention relates to vacuum and flushing a paratus of the character shown and desert ed in the accompanying drawings, to be applied to toilet fixtures, the vacuum being produced by the construction of an electric fan, applied in the vent or escape pipe of the fixture. A flushing apparatus constructed of a cylinder form with piston connections provided with port and exhaust to receive and discharge water under pressure, working systematically from either side, and operated by means of a lever.

The object of my invention is to produce an economically constructed vacuum and flushing apparatus for toilet fixtures, that is perfect in its operating and sanitary qualities.

In carryingout my invention I do not wish to be understood that it is confined to the details shown by the accompanying drawings.

1 than the particular embodiment herein presen-ted and described, and embraces in construction and mechanism that which comes within the scope of the claim.

In the drawings, Figure 1 shows an end and sectional view of a flushing apparatus, cut in two on line 12. Fig. 2 is the center part of the flushing cylinder, containing the ports and acts as a separating appliance for the two parts of the cylinder. Fig. 3 is a side and sectional view of the flushing cylinder complete, cut in two on line 3-4. Fig. 4 is a top view of the flushing cylinder, dotted lines representing the inner working ports of the cylinder. Fig. 5 is a side and sectional view of a toilet fixture with the vacuum and flushing. a aratus applied,

constructed in a perfect working form. F ig. 6 shows the manner in which the cylinder is placed between the fixture and the wall. Fig. 7 is a part of the fixture withlid appliances attached to show the manner of applying the same.

similar letters refer to similar parts throughout the several views.

A is the shell of the cylinder.

B are the heads of the cylinder.

The inventive idea is broader C' are holes in the flan e ofthe cylinder through which bolts'may e inserted to fasten the heads of the cylinder on.

D 1s the discharge pipe,'attached to the bottom part of the cylinder.

E is the receiving pipe which is fastened to the cylinder by bolts F.

G are "plates which 'form a (sieparating and center sectiono the cylin-. -er."' w

g are arrowheads, showing the direction of the flow of water.

H is the separating and'center section of the cylinder.

J is a discharge port of the cylinder.

K is the receiving ort. t

L are holes provi ed for bolts to fasten the center separating head in the cylinder.

M are the piston heads.

N is the piston rod.

0 is a packin ring or gasket, attached to each piston hea M.

P are the iston rod stufling boxes.

Q are stu 11 box fa'stenings.

R is the stu ng box packing.

S is a lever used to operate the valve connections and piston appliances.

T is the vent pipe, provided with a sleeve U.

V, is the casing or inclosure of the fan. W 1s a door or opening to the fan inclosure.

X is the fan.

Y is the flushing appliance.

Z --is one part of the cover or lid of the flushing a pliance.

-a is the --id.

1) and d are the hinge connections to the lid'and cover appliance.

e is a button connection on the wall, also on the flushing apparatus.

7 is the electric wires thatconnec't the current of electricity at points 6 to operate the fan.

h is a conical shaped rim on the inner part of the flushing appliance.

When the handle S is grasped by the operator to throw the central section of the cylinder to the position illustrated in Fig. 3, water under pressure through one of the ports K, (see Fig. 2) passes to the right hand end of the cylinder A driving the water contained between the left hand piston M and the central section ofthecylinder is art of the I right hand piston M toward the right. 'The x driven out through pipe D, (see Figs. 3 and 5) and is caused to overflow into the bowl. When the handle is thrown in the o posite direction the other port K brings t e left hand end of the cylinder into communication with the inlet pipe E and the left hand piston is driven toward the left. At this time the other port J shown in dotted lines in Fig. 1, is establishing communication between the ri ht hand end of the cylinder in Fig. 3 and tie pipe D. The water' between the right hand piston M and the central portion of the cylinder will now be driven out from the pipe D and overflow into the bowl. It will therefore be seen that the resent invention provides a very simple an efiicient means for forcing a redetermined amount of water into the bow each time the handle S is moved in either direction. It will also be seen that an electric circuit to the fan X will be closed when the push button E is actuated or when the cover A of the bowl is lowered to bring the contact points e into engagement with each other.

I claim- Ina device of the character described, the

combination with a bowl, of a conduit leadthe cylinder and theconduit, and when said section is at its opposite limit of movement establish communication between the left hand end of the cylinder and a source of water supply and establish communication between the right hand end of the cylinder and the conduit, a piston located in said cylinder upon each side of said central section,

a piston rod connecting said pistons, plates G spanning said cylinder and holding said central section in position, and packing members carried by said plates which form a fluid tight packing about said piston rod.
